1、系统环境

操作系统：Windows11

虚拟机VirtualBox6.1：Downloads – Oracle VM VirtualBox

Ubuntu18.04.6: https://releases.ubuntu.com/18.04/ubuntu-18.04.6-desktop-amd64.iso

VirtualBox主机与虚拟机不能复制粘贴的解决办法，要开启两项：

第1项：安装增强功能

第2项：选中使用主机输（I/O）缓存

2、GDB8.2 带python功能

a@sys:~$ gdb
GNU gdb (Ubuntu 8.1.1-0ubuntu1) 8.1.1

Type "show configuration" for configuration details.

(gdb) python
>import os
>import sys
>print(sys.version_info)
>end
sys.version_info(major=3, minor=6, micro=9, releaselevel='final', serial=0)
(gdb) 

如果gdb本身没有带python，需要自己安装，过程中注意事项如下：

安装Python2.7出现如下错误：

The following packages have unmet dependencies:
 python2.7 : Depends: python2.7-minimal (= 2.7.15~rc1-1) but it is not going to be installed
             Depends: libpython2.7-stdlib (= 2.7.15~rc1-1) but 2.7.17-1~18.04ubuntu1.6 is to be installed
E: Unable to correct problems, you have held broken packages.

则执行下面的安装命令：

sudo apt-get install aptitude

sudo aptitude install python2.7

其他辅助命令：查看进程的绝对路径

ll /proc/pid

sudo aptitude install gcc    输入 n y y 

sudo apt-get install g++

sudo apt-get install python2.7-dev

sudo apt-get install texinfo

wget http://ftp.gnu.org/gnu/gdb/gdb-8.2.tar.gz

tar zxf gdb-8.2.tar.gz

sudo aptitude install make

gdb-8.2$ ./configure --with-python='/usr/bin/python2.7'

3、安装Android Studio

安装sdk ndk avd

设置$PATH

a@sys:~$ cat ~/.bashrc

export PATH=~/Android/Sdk/platform-tools:~/Android/Sdk/emulator:$PATH

开启虚拟机CPU VT虚拟化，并赋予kvm权限:

sudo chown a -R /dev/kvm

4、下载安卓内核源代码

repo init --depth=1 -u https://android.googlesource.com/kernel/manifest -b q-goldfish-android-goldfish-4.14-dev
